If you have an iPhone SE Gen 3 (Or any other iPhone with TouchID, but models older than the SEGen3 have other weaknesses to worry about), you can do the same by spamming the power button 5 times.
You can also ask Siri to reboot or turn off your phone, Siri will ask you to confirm you want to do the action, but it doesn't take too long to do. Just in case you don't want to reach for your phone for what ever reason.
